Baking soda is a very mild alkaline powder, which is slightly corrosive when dissolved in water, and it is easier to remove dirt than clear water. In addition, baking soda powder can produce carbon dioxide when it meets water, which can produce stirring effect, so baking soda can play a role in slightly dirty places or objects, especially those who are allergic to detergents. You can add a little baking soda to the dishwashing water, so it won't burn your hands, and you can also wash the dishes and plates very clean.
